Answer:
complementary angles
one angle measures 22�more than the other
Let x represent the smaller one
x + (x+22) = 90
2x = 68
x = 34, the smaller, 56 the larger
34 + 56 = 90 CHECKS!

Answer:
To find the maximum of a function in ax^2 + bx + c form, you can use the formula: maximum = c - (b^2 / 4a).
In this question, a = -16, b = 180, and c = 63.
Maximum = 63 - (180^2/4(-16))
Maximum = 569.25
Finally, rounding this to the nearest tenth of a foot, the final answer is 569.3 ft.

Answer:
290
Step-by-step explanation:
60% of ⅔X = 174
60/100 × 2/3 × X = 174
⅖X = 174
X = 435
⅔X = ⅔×435
290

Answer:
Length = 90 inch.
width = 30 inch
Let width of the rectangle = x inch.
So the length = 3x inch.
Perimeter = 2(length + width) = 2 (3x + x) = 8x.
So,
length = 3x = 3(30) = 90 inch.
width = x = 30 inch
